How to whiten underarm, whole body and the face?

Well for the underarms it is best to stop shaving as this is the main cause of colour discolouration on that part of the body. Try waxing instead, also use a moisturising underarm perspirant. For the face you can buy creams but they are not recommended as they can prove to be more harmful than anything. There may be creams for the body too but I wouldn't advise them either.

If you are really upset and would like to seek treatment then look for a really good dermatologist, as only they can provide safe treatment
